Preheat the oven to 325°F (163°C). Grease a 9-inch springform pan.
In a medium bowl, combine graham cracker crumbs and melted butter. Press mixture firmly into the bottom of the prepared pan.
In a large mixing bowl, beat the cream cheese and sugar until smooth and creamy.
Add sour cream, eggs, and vanilla extract, mixing until just combined. Do not overmix.
Pour the batter over the crust and smooth the top.
Bake for 50-60 minutes, or until the center is just set and the edges are lightly golden.
Turn off the oven and let the cheesecake cool inside for 1 hour with the door slightly open.
Remove from the oven, cover, and refrigerate for at least 4 hours or overnight.
Before serving, spread strawberry jam over the top and arrange fresh strawberries decoratively.
